Simply the best strategy game you can buy...ever...ever.
Where can I start!? The battles that you fight are simply incredible! All those triarii spearmen, velites and onagers galore to command at my finger tips! The adviser can be quite annoying but at first he is actually useful if you listen to him, I learnt that using fire arrows, for example, can weaken enemy morale. It actually feels almost real because the units can get tired the more they fight, and as numbers decrease, they become less efficient etc. The best part about battles, personally, I think is shooting the charging enemy down with hundreds of flaming arrows!
If fighting isn't your thing, then city building is sure to put a smile on your face! After all, you need these building to produce magnificent armies! You don't have to fight, you can choose to automatically resolve battles if you wish, just be sure your doing the right thing, sometimes it's a lot easier doing it yourself. The different buildings can affect your people, like placing a shrine to Jupiter can make people happier, for example. Again though, the adviser is quite annoying.
The only bad points I have to point out is that the advisers are quite annoying after a while, eventually you will hear the same things over and over and over again. Also, there are all these scrolls and graphs and information that are pretty pointless but do make it seem very challenging and realistic.
Overall, bad points aside, if you love Romans, strategy games or need to pass by a lot of time this is the game for you!
